Boiler-feeder.



NITnD STATES f RUTHER'MCDOUGALL, or Dns MOINES, IOWA.

SPECIFICATION forming' part Of Letters Patent No. 652,1 34, dated June 19, 1900.

Application filed April 5, 1900.

To @ZZ whom, it may concern.-

Be it known that I, RUTHER McDoUeALL, a citizen of the United States, residing at Des Moines, in the county of Polk and State of Iowa, have invented a new and useful Improvement in Boiler-Feeders, of which the following is a specilication.

My objects are, first, to combine a siphon and an injector for feeding water to a loco1notive-boiler, and thereby overcoming the. difficulties incident to drawing water from a tank when the supply is low and the locomotive on an inclined grade, so thatthe water remaining in the tank will not cover the outlet where the hose is attached; second, to connect the injector with the boiler and the siphon with the tank in such a mannerqthat the engineer in the cabin can operate them jointly for feeding the boiler and also for cleaning the pipes and hose to prevent the accumulation of sediment in the boiler and tank, and, third, to prevent leakage and waste of water and damage to hose incident to water freezing in pipes and hose.

' My invention consists in the arrangement and combination of parts. as hereinafter set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which- Figure lis a side elevation of parts of a locomotive-engine and tender, showing portions broken away and the relative positions of the different operative parts. Fig. 2 is an enlarged section of the tank, showing the manner of combining a siphontherewith and means for removing water from the siphon and also from the tank. Fig. 3 shows a section of the tank.

The letter A designates the tank, and B a Siphon fixed to the roof of the tank by means of a U-shaped screw-bolt and nuts. A petoock c at the top of the siphon allows air to be admitted into the Siphon as required to allow Water to empty therefrom into the tank and to make the siphon inoperative.

D is an elbow-shaped pipe extended up through the bottom of the tank and connected with the siphon by means of a coupling D2 or in any suitable way. A branch f eX- tends upward from the pipe D through the bottom of the tank and has avalve-seat f at on top of the roof its top. A screw-seat f Serial No, l 1,599. (No model.)

of the tank su pports a screw-threaded valvestem f", that terminates in the bottom of the tank, and has a valve g fixed thereto that its the valve-seat in such a manner that the valve can be readily operated, by means of a crankhandle g at the top of the stem, to open the branch pipe f as required to allow water to pass through from the tank for the purpose of emptying and cleaning the tank.

H represents a section of hose connected with the end of the pipe D and adapted tobe detachably connected with a mating section of hose-section H2 by means of a hose-coupling H3.

J represents the cabin, and J2 the boiler, of a locomotive-engine, and K an injector connected with the boiler. The hose-section H2 is xed to the bottom of the injector and detachably connected with the hose-section I-I by means of the coupling H2.

K2 is a pipe extending from the injector to the front and lower portion of the boiler. A valve Z opens and closes communication between the boiler and the injector. A valve Z opens and closes communication between the injector K and pipe K2. A valve Z opens and closes communication between the injector and a Waste-pipe m, and a valve 'm' opens and closes communication between the injector through the hose H and H2 and the siphonB with the tank A.

In the practical use of my invention when the petcock c, the valve g, andthe valve Z are closed and the valves m', Z", and Z are opened the force of the steam escaping through the injector and valve m' will by suction draw water from the tank and into the hose np to the valve m', and as quick as any escapes through the valve Z" that valve must be closed and the valve Z' opened, so that the force of steam will press water through the pipe K2 into the boiler as required to feed water from the tank to the boiler, and by closing the valve Z' the water remaining in the injector and the hose will be pressed back through the siphon into the tank, so that the hose can be uncoupled without wasting any water.

It is obvious the hose and pipe and siphon may be cleared of any sediment that may gather therein by the same manner of backward steam-pressure directed from theboiler IOO l. In a Water-tank for alocomotive steam- 1 engine, a siphon fixed in the tank and one end extended through the bottom of the tank, a section of hose attached to said end ot'A the siphon, an injector connected With the boiler, a section of hose connected with the injector and a coupling for connecting the tWo sections of hose, arranged and combined with the cabin and tender of a locomotive-engine to operate inthe manner set forth for the purposes stated.

2. In the tank of a locomotive-engine, a fixed siphon, an elbow-shaped pipe extended from one end of the Siphon through the bottom of the tank, a branch pipe extended from the elbow-shaped pipe up through the boty tom of the tank, a valve-seat at the top of said branch, a valve fitted to said valve-seat and provided With a stern extended up through the top of the tank, arranged and combined to operate in the manner set forth for the purposes stated.
